OBJECTIVE: Because of its anti-inflammatory, anti-fibrotic, anti-apoptotic and anti-neoplastic properties, the PPAR-γ agonist rosiglitazone is an interesting drug for investigating for use in the prevention and treatment of radiation-induced intestinal damage. We aimed to evaluate the radioprotective effect of...

Degradation of lignin constitutes a key step in processing biomass to become useful monomers but it remains challenging. Compared to fungi, bacteria are much less characterized with respect to their lignin metabolism, although it is reported that many soil...

Organocatalyzed Multicomponent Synthesis of Isoxazolidin-5-ones.

Organic letters

Berini C, Sebban M, Oulyadi H, Sanselme M, Levacher V, Brière JF.

Org Lett. 2015 Nov 06;17(21):5408-11. doi: 10.1021/acs.orglett.5b02755. Epub 2015 Oct 21.

An unprecedented multicomponent organocatalyzed Knoevenagel-aza-Michael-cyclocondensation reaction between Meldrum's acid, hydroxylamines, and aldehydes afforded a straightforward entry to a large array of racemic and syn-diastereoenriched isoxazolidinones as synthetically useful scaffolds. This process revealed a markedly facile aza-Michael-cyclocondensation sequence as a...

Undifferentiated Pleomorphic Sarcoma and the Importance of Considering the Oncogenic and Immune-Suppressant Role of the Human T-Cell Lymphotropic Virus Type 1: A Case Report.

Frontiers in oncology

Front Oncol. 2017 May 24;7:91. doi: 10.3389/fonc.2017.00091. eCollection 2017.

INTRODUCTION: Soft-tissue sarcomas account for 0.7% of all malignant tumors, with an incidence rate of 3 per 100,000 persons/year. The undifferentiated pleomorphic sarcoma (UPS) with giant cells, a high grade tumor of soft tissue, is very unusual, especially in...

Nanoscale Schottky contact surface plasmon "point detectors" for optical beam scanning applications.

Applied optics

Othman N, Berini P.

Appl Opt. 2017 Apr 20;56(12):3329-3334. doi: 10.1364/AO.56.003329.

We propose and investigate a Schottky contact detector where the contact metal is a nanoscale metal stripe waveguide supporting surface plasmons with strong localization along the Schottky contact. We consider Au for the metal stripe, p-doped silicon for the...

Theoretical performance of Bragg gratings based on long-range surface plasmon-polariton waveguides.

Journal of the Optical Society of America. A, Optics, image science, and vision
